Reading and Writing

Writing a paragraph

Build a paragraph from a topic sentence, supporting sentences and a closing sentence, and keep everything in it about one idea.

A paragraph is not just a lump of text with a gap before it. It is one idea, worked through from start to finish, in a shape a reader can follow without being told what the shape is. Three kinds of sentence build it.

The topic sentence opens the door

It says what the whole paragraph is about, and it usually comes first. It has to be broad enough for everything that follows to fit under it — "A market at dawn is a busy place" can hold a whole paragraph; "I bought two mangoes there" cannot.

The supporting sentences do the work

Reasons, examples, facts and details — three or four of them, each one backing up the topic sentence. This is the middle of the paragraph and most of its length.

The closing sentence ties it off

It looks back over what has been said rather than starting anything new: So the river shapes almost everything the village does. Words like so, in all these ways and for all these reasons are how it signals that it is closing.

Unity — one idea, and only one

Every sentence in a paragraph must be about the topic sentence. A sentence that is perfectly true and quite interesting still has to go if it belongs to a different idea. That is the hardest rule to obey and the one that most improves writing.

Coherence — each sentence leads to the next

Unity is the paragraph holding one idea; coherence is the sentences holding on to each other. Linking words do it: however, therefore, for example, in addition, finally.

Worked example

Which sentence has to go? "Cycling is good for a town. It costs nothing to run. It takes up little space to park. My uncle bought a red car last year. It also keeps the air clean."

  1. Find the topic sentence: "Cycling is good for a town."

    Everything else has to fit under it, so it is the ruler you measure the rest against.

Try it together

Let us name the three parts of a paragraph.

The paragraph is about why the school garden is worth keeping. Each answer is one word.

    1.The first sentence tells the reader what the whole paragraph is about. What is that sentence called? Write one word.
